Application filed March 13, 1913. Serial No. 753,925.

To all whom, it may concern:

Be it known that I, OSCAR H. STUEWE, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of lVisconsin, have invented new and useful Improvements in Wire Mattress Fabric, of which the following is a specification.

My invention relates to improvements in a certain wire mattress fabric for which Letters Patent of the United States, numbered 10416233, was issued to me December 3, 1912. By the wire mattress fabric shown in said patent, the two longitudinally arranged side wires of each link are connected together by a single transversely arranged member and two loops, which loops are so bent as to contact with the two side wires at an acute angle to said transverse member, and the diameter of said loops is considerably greater than the diameter of the hooks of the next adj acent links which are inserted through them. The respective series of links are also shown as connected together at short intervals apart by transversely arranged short links. In view of the fact that in securing the short links in place it is necessary to slip them over the ends of the loops at their largest diameter, it became necessary to make such links of greater length than the widest diameter of such loops. It therefore follows that when said links are in place, as shown in said patent, they have too much freedom of movement and are liable, for such reason, to get out of place.

The object of my present improvement is, therefore, to so shape the loops and central member that the transverse links, by which the longitudinal links are connected together, will bear with increased force against the loops as they are brought into place against the transverse members.

A further object of my invention is to so construct the loops and the transverse links that the respective hooks formed on the ends of the longitudinal links will fill the space between the opposing surfaces of said loops and transverse links whereby said links will be securely retained in place.

My invention is further explained by reference to the accompanying drawings, in which Figure 1 represents a plan view of a portion of a mattress fabric formed of a plurality of links connected together, and Flg.

2 represents a side view of the parts shown. in Fig. 1.

Like parts are referred to by the same reference numerals in both views.

' The main body of the mattress fabric is made up of a plurality of longitudinally arranged wire links 1. Each link 1 comprises two side members 2, 2, which side members 2 are each respectively provided at their ends with hooks 3 and the opposite ends of said members are connected together by transverse central members 4 and loops 5 formed for the reception of the hooks 3 of the next adjacent link, and the several longitudinal series of links are connected together at their junctions by the transversely arranged short links 6. The ends of the transversely arranged links 6 are bent so as to abut against each other, as shown at the point 7 in Fig. 1. The relative length of the links 6 to the loops 5 is such that said links 6 are adapted to closely fit and bear against the inner sides of the two opposing loops, when the two opposing side members of each link are in contact, while the inner portion of the respective loops 5 of each link 1 converge inwardly, whereby said transversely arranged short links 6 are adapted to bear firmly'at their inner ends against the opposing surfaces of said loops 5 and whereby suflicient space only is left between said transverse short links 6 and the ends of said loops 5 for the admission of the hooks 3. Thus it is obvious that when said links 6 have been forced over the diverging loops 5, they will be securely retained in place by contact with the hooks 3 formed on the respective side members of the links 1, and whereby said cotiperating parts will be prevented from rattling or getting out of their proper relative positions to each other.

It will be understood that the body of the mattress fabric is formed by connecting a plurality of series of links 1 together by a plurality of transversely arranged short links 6, and that the fabric forming such body is connected at its respective ends'to the respective end members of a mattress frame in the ordinary manner.

Especial attention is directed to the fact that the hooks 3 when in place, contact upon one side with thetransversely arranged short links 6 and upon their opposite sides with the loops 5, and no space is left between the contiguous surfaces of such links, hooks and loops, as is more clearly shown in Fig. of the drawings. By the construction shown in said patent, the loops formed for the reception of said hooks are several times larger than the diameter of the hooks, whereby when the hooks are in place, the transversely arranged links are liable to accidentally get out of their proper position, while by the present construction, the transversely arranged links are retained by said hooks in impinging contact with the opposing surfaces of said loops and the several cooperating parts are thereby securely retained in place.

For brevity of description, the links 1 are referred to in the claims as the long links and the links 6 as short links.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is

1. In a mattress fabric of the described class, a plurality of long links having two hooks formed at one of their ends, a transverse central member and two loops diverging inwardly toward each other at their opposite ends, in combination with a plurality of transversely arranged short links, the ends of which surround and inclose the two next adjacent loops of the two next adjacent long links, the hooks on said side members of the long links being inserted through the inwardly diverging loops of the next adjacent link in alinement therewith, said hooks being adapted to retain said short links in. binding contact with the inwardly diverging loops inclcsing the same.

2. In a mattress fabric of the described class, the combination of a plurality of longitudinal rows of interlocking long links, each link comprising two side members, a hook formed on the end of each side member,. a transverse central member, two U- shaped diverging loops 5, and a plurality of transversely arranged connecting short links connecting the sides of the next adjacent long links of the respective series, the opposing inner surfaces of the respective short links being adapted by the diverging shape of the diverging loops to bear against and be retained in place by such diverging loops of the two next adjacent long links and by the impinging contact of the hooks formed on the ends of the side members of said long links.

In testimony whereof I aflix my signature in the presence of two witnesses.
